Right Angle Planetary Gearboxes
Our right angle planetary gearbox series delivers output torque at exactly 90° to the input shaft — combining a multi-stage planetary reducer with a spiral bevel output stage. Two series available: EP300R (16 frame sizes up to 500,000 Nm) and NB300R (12 frame sizes up to 450,000 Nm). Every unit 100% load-tested before shipment.
What Is a Right Angle Planetary Gearbox
— and When Do You Need One?
A right angle planetary gearbox adds a spiral bevel gear stage at the output of a standard multi-stage planetary reducer, redirecting output torque to exactly 90° relative to the input shaft. This is the defining difference from an inline (coaxial) planetary gearbox — and the reason engineers specify this type when a machine’s geometry makes in-line shaft arrangement impossible.
The spiral bevel output stage matters: progressive tooth contact reduces noise and vibration versus straight-cut bevel designs at equivalent torque ratings — an important consideration for equipment installed in occupied structures, greenhouses, or noise-restricted industrial environments.

Replacement Brands
Our planetary gearboxes are engineered to match the key specifications, dimensions, and performance characteristics of leading international brands, enabling seamless one-to-one replacement.
All mounting interfaces and overall dimensions are developed in strict compliance with the standards of major Italian and American manufacturers. As a result, our gearboxes offer full interchangeability in both performance and connection compatibility with Brevini ED, ET, EQ, EM, EC, and EL series, as well as Bonfiglioli 300 series and Dinamicoil RE and RA series. This makes them a reliable and cost-effective alternative to original Italian products.

Frequently Asked Questions — Right Angle Planetary Gearbox
What is the price difference between a right angle and inline planetary gearbox at the same torque?
A right angle planetary gearbox typically costs 8–15% more than an equivalent inline unit at the same torque rating, due to the additional spiral bevel gear stage. In most applications, this premium is offset by the elimination of costly right-angle adaptor brackets or custom shaft couplings. Contact us for a direct price comparison for your specific torque and ratio requirement.
What is the efficiency loss through the bevel stage in a right angle planetary gearbox?
The spiral bevel output stage adds approximately 2–3% efficiency loss per pass. For a 3-stage planetary unit with a bevel output, total efficiency is typically 94–96% — versus 97–98% for a comparable inline planetary unit. For most industrial and mobile equipment applications, this difference is negligible relative to the layout flexibility gained.
Can I order a right angle planetary gearbox replacement for Bonfiglioli without sending drawings?
Yes — in most cases the nameplate data is sufficient. Send the brand name, series code, gear ratio, output torque or frame size designator, and input/output configuration. We cross-reference against our compatibility database and confirm the matching EP300R or NB300R variant within 4 business hours. For unusual or non-standard configurations, a dimensional drawing of the critical interfaces may be requested.
Are non-standard gear ratios available in the EP300R right angle gearbox?
Non-standard ratios within the production range (6.9:1 to 9,000:1) are available to order with a 10–35 day lead time. Specify your required output RPM and input motor speed — we’ll calculate the exact ratio and confirm the nearest standard option or advise on a non-standard production run depending on quantity and urgency.
What documents are included with a right angle planetary gearbox shipment?
Every order includes: signed load test report, commercial invoice, packing list, and bill of lading. Certificate of origin, CE declaration, and ISO 9001:2015 conformance certificate are available on request at no additional charge. All documentation is provided in English.
